As part of the BTS Commerce International curriculum, students are required to complete an 8-week internship during their first year, with a minimum of 4 weeks abroad, followed by a second 6-week internship in the second year, either in France or abroad. Our educational policy strongly encourages students to complete the entire first-year internship abroad, and to go abroad again in the second year whenever possible. This Erasmus+ KA131 project addressed several key goals, combining an inclusive approach with a clear commitment to the internationalisation strategy of our institution: Supporting the completion of these mandatory international internships through Erasmus+ grants, with the aim of removing financial barriers to mobility (particularly relevant in our region) and ensuring equal opportunities for all students to gain international experience. Strengthening the European and professional dimension of the training, in direct alignment with the goals of the BTS Commerce International framework, which values the development of intercultural and language skills through real-world experience. Promoting study mobilities, despite the challenge of the recognition of the BTS degree across the European higher education field. Thanks to new partnerships with institutions in Spain, the Netherlands, and Finland, we were able to organise several student study mobilities. Enabling staff members (both teaching and management) to carry out monitoring mobilities, through visits to internship locations to secure long-term cooperation with host companies and to initiate partnership projects with foreign schools. These field visits are essential levers for the development of future study mobilities or cooperation projects such as KA2. Providing professional development opportunities for staff, allowing them to enrich their teaching practices, gain deeper insight into foreign professional contexts, and reinforce partnerships with a focus on quality and sustainability. This project has been a structuring milestone in our institution’s European development strategy, aiming to anchor international mobility as a tool for student success, staff professional development, and the global outreach of the school. It builds on previous Erasmus+ actions and our ECHE commitments, while enabling us to make further progress in student support and in building new international partnerships. Moreover, it fits into a broader transversal dynamic, creating strong synergies with other Erasmus+ initiatives in our institution (such as mobilities for vocational education, KA122 and KA220 partnerships), and thereby contributing to the development of a shared and recognised culture of internationalisation across the entire school community.
